limitation tiled september 21,1189?. serrant. 652,500. (romana Be itknown that I, JOSEF KORBULY, a subject of the Emperor' ofAustria-Hungary, residing at Arad, Austriallungary, have inventedcertainllinprovements in the Bearings Ido hereby declare the followingtobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification.

This invention is an improvement on the No. 558,'693,dated `April 21,1896, and has for its object increased facility in the lubrication ofthe journal and bearings, as well as greater simplicity and compactness.

In the accompanying drawings, Figure l represents a longitudinalverticalV section of a journal-box and inclosed parts embodying myinvention, the journal being shown in side elevation. Fig. 2 representsa central transverse section of the same. Fig. 3 represents a transversesection of the same, taken on a plane at the inner edge of the washersand looking outward. Fig. 4 represents a detail sectional View of ltheunder part of the washer and devices for holding it in place. Fig. 5represents a view, similar to Fig. 1, of a slightly-modified form of mydevice. Fig. 6 represents a view of thesame similar to Fig. 3. Fig. 7represents a detail View, similar to Fig. 4, of the modified' form ofwasher and clamping devices illustrated in Figs. 5 and 6. Fig. 8represents a view, similar to Figs. 1 and 5, of another modication. Fig.9 represents a detailview, partly in elevation and partly in section, ofthe washer, tightenin g-nut, and proximate devices. Fig. 10 represents adetail view of the said tightening' nut, its screw, and the frame orcasein which it works, the parts having the construction shown in Fig.1.' Fig. 11 represents a view, similar to Figs. 1, 5, and 8, of anothermodiiication. Fig. 12 represents a transverse central section of Fig.11. Fig. 13 represents a side elevation of another modification withinterior parts indicated by dotted lines; and

oil-reservoir.

Fig. 14u representsa vertical section through Fig. 13, taken at the rearend of the brasses. In practical use of my devicesshown in vPatent No.558,693 I have found that the jou mal-bearings wear very little, so thatthere is no great needv to make them rotatable. Also I have found thatthe rapid rotation `of the axle-journal in the bearing-brasses forms apartial vacuum in the narrow interval between them, so that the oil issucked up from below to the journal if any passage be left for it. Toutilize this latter fact and in view of what is above stated vwithregard to the bearings, as Well as for the purpose of permitting theboxes of car-axle journals to be manufactured more cheaply and simplythan heretofore, I have invented the following construction.

A designates the journal-box, inclosing the journal C of the car-axleand the bearingbrasses d d, the said box resting on the uplper brass CZ,to which the upper part of the" said box is fastened by screw t in theforms of my invention illustrated by Figs. 1, L and 5. The body A ofthis box is cylindrical and fits the said brasses closely. Anoil-reservoir B below the said body and also extending up outside theend of the journal is provided with a thin outer shell D, which isintegral with the said body and forms a part of the said box. This shellis curved transversely, as shown in Fig. 2, and also longitudinally, asshown in Figsl, 5, and S, giving it a peculiar shape corresponding to alongitudinal semicylindrical sectionv of a pipe running along the underside of the said box-body and bent up to cover its outer end, whichwould otherwise be open. 'The lower brass or bearing cl' is providedwith a central funnel-like aperture Z3, which communicateswith the upperend of the central bore l of a tube Z, the latter being cast with thebox-body A' and extending downward therefrom into the said The oil isfed tothe said reservoir through holes in the top of the said box, nearthe ends thereof, one of which (marked m2) is shown in Fig. 8.V 0ne ofthese is normally closed by a plug m and the other by a screw m. Thesuction due to slight irregularities in the running of the journal drawsup the oil to the said journal through the pas- IOO . plate into thesaid box.

Figs. 13 and 1l.

11 and l2, or by outer encircling rings z .2',

ThislowerbearingD"is provided with the downwardly-extending tube t toni.

, and its bore l' of Fig. As shown in Fig. il, the journal-box used withthis modification of my invention does not correspond to the journal orbearing, but is flat at the botlt has no auxiliary shell D, but iselosed 'i at the end and adapted to hold oil, so that the j operation isthe same as hereinbefore deof the said box and a fastening-plate yr, bymeans of a bolt r, that passes through the said I also employatightening-ring 0, surrounding the [lat horizontal part ot the saidwasher, as shown in section in Figs. l and 4, and tightened by a nutg/and serewf, the latter working through a tixed part of a easing or framee, whieh is integral with the said axle-box. These tightening dovioesare most distinctly shown in Figs. 10 and Il.

The washer thus held in plaee and tightened prevents the oil frompassing out of the inner end of the journal-box and along the axle or onthe ground below.

In journal-boxes itting close to the outer face of the wheel E, as shownin Fig. 5, I substitute for the said ring r a grooved eollar y, whieh isserewed to the innerend of the axlebox and allows the latter to be madeshorter,

a leak-preventing washer s' (see also Fig.

being held in plaee by the said collar.

As shown in Fig. S, the box-body A soine scribed.

Having thus described my invention, what I olaim as new, and desi re toseeu re by Letters latent, is-

l. A journal-box provided with a reservoir for oil extending below thesaid box, a perforated bearing for the journal, and a tube eX- tendingdownward into the oil and affording a passage for the same up throughthe aperture of the hearing to the journal substantially as set forth.

L. An axle-box provided with a cylindrical body A and a shell forming anoil-reservoir below the latter, in combination with a brass d within thesaid body and a tube extending down from said body into the oil, thebore of the said tube and a registering aperture in the said brassaffordinga continuous oil-passage to the journal, substantially as setforth.

3. In combination with 'an axle-journal and its box, an oil-retainingannular washer tting on the said journal and provided with a times alsoserves for a bearing, the ordinary brasses being dispensed with. In thisease the central bore of tube l extends to the journal and has afunnel-shaped top. On aeeount of this dii'lerenee in Construction I havemarked the said bore Z in the said figure.

In journal-boxes having an upper brass D', Figs. 1l, l2, 13, and ll, butno lower brass, I attach to the upper brass a lower semieylindriealbearing D, which is fastened to the said upper brass by lugs 7n andbolts 7s, Figs.

I' i t vertieal part, and a retaining-plate and bolts whereby the saidVertical part is clamped to the inner end of the said box, substantiallyas set forth.

In witness whereof I have hereunto set my hand this 31st day of July,1897.
